HI, Sorry for the english, but you guiys will probably get more from it than a google translation.. I have a Quattrini M1 (without the L) kit which i have run for several years and then put in a box due to it needing a re-plate and rode my raised polini. I now want to see what I can do with the M1, prior to getting it replated in preperation for a sprint meet in September. I would require the bike to still be rideable in town, I know it will be feisty, but I like to ride WOT anyway.. So, I have the M1 kit, and with it set for a squish of 1.03mm (maybe a little low) I have timings of 125/177 and an inlet time of 110 before and 66 after tdc giving a total of 176. with 129fully open. I have fiddled with the exhaust port when I got it and its not far of 70% as is already before raising it. I also have the seigorini JL pipe for the M1 (without the L) and a Franz. (which would you use and why?) So the question is, what would folk recomend I could do to it, that would get me to nearer 80mph on a standing quarter, but still enable it to be ridden (all be it quickly) round a city. Could I just raise the exhaust port a mm or 2 to get nearer 180 there? or do I need to stroke it? or is it top and tail and a hugh packer? which pipe ( I know if I go for the franz I will not be able to go back so maybe try it with the dedicated pipe first due to header size? Any thoughts or suggestions greatly recieved. Cheers
